Well it depends. If you were at a stable point in life I see no reason you couldn't take a couple pills as often as you did for as long. If there is anything you need to deal with like school, tough relationship issues, finding a career, stuff like that, it makes it really hard/impossible to cope.
I had a similar 6+ months which I considered to be quite an abuse of the drug. Weekly or bi-weekly dosing, sometimes 5 or more doses in a night, sometimes multiple grams in multiple days, snorted tons of pills and crystals, tons of alcohol, dehydration, barely any responsible eating, no exercise, etc. My tolerance went up but not too much. One pill would still feel the same, I would just desire to roll harder than I was used to rolling. A lot of these tolerance problems are in peoples head (looking at you rickolasnice). The last time before quitting the honeymoon I rolled hard for 2 straight days. Personally, I don't really get this severe tolerance problem stuff. If that couldn't make someone "lose the magic" then I don't know... I had to stop because I felt like I was going crazy, and because I was running out of money (too many 300 dollar weekends), not because the drug wasn't working anymore, it definitely was.
